Dear PCE WG,
I support PCEP-LS in the PCE WG. PCEP-LS is one of the most efficient and cost-effective ways to migrate legacy networks into software-defined networks, because a lot of packet devices and optical devices already have supported PCEP. Besides, PCEP-LS could be adopted into existing devices and even packet or optical controllers easily and quickly. As you know, both ONOS and ODL have supported PCEP protocol which is mature technology. And we showed how easily we can have implemented PCEP-LS by modifying open source of PCEP module in our ONOS-based controller (MDSC) which was demonstrated during IETF 97 B&B. We interfaced packet PNC as well as optical PNC and supported PCEP-LS for both cases. In our commercial networks, we have already deployed our transport infrastructure orchestrator which is the top of MDSC based on ODL supporting PCEP. Our orchestrator will support both PCEP-LS and RESTconf for packet and optical PNC. Best regards, Jongyoon Shin From: Pce [mailto:[email protected]] On Behalf Of ???

The inter-operability of PCEP-LS was demonstrated across ETRI, KT and Woori-Net. I support PCEP-LS to be adopted in the PCE WG. We think that PCEP can provide one of ways to implement all of the main functions of SDN controller. So, we want PCE WG to provide a total solution to implement SDN controller as much as it can rather than using other WG's protocols such as BGP-LS. Thanks.

During IETF B&B in Seoul, KT demonstrated resilient ACTN architecture with ETRI and other vendor using PCEP-LS using PCEP-LS for packet optical network to quickly determined network failure and reported to the MDSC using PCEP Report mechanism. I believe PCEP-LS is an important work for us. And I strongly support PCEP-LS to be considered as PCE WG’s WG item Thank you, Peter ======================================================== Dr. Peter(Choongul) Park Senior Researcher / KT Infra Lab. 463-1 Cheonmindong Yuseonggu Daejeon Korea(South) T: +82.10.2879.7463 / F: +82.42.870.8089 이 메일은 지정된 수취인만을 위해 작성되었으며, 중요한 정보나 저작권을 포함하고 있을 수 있습니다. 어떠한 권한 없이, 본 문서에 포함된 정보의 전부 또는 일부를 무단으로 제3자에게 공개, 배포, 복사 또는 사용하는 것을 엄격히 금지합니다. 만약, 본 메일이 잘못 전송된 경우, 발신인 또는 당사에 알려주시고, 본 메일을 즉시 삭제하여 주시기 바랍니다.
